A friend of mine has a 94 Prowler w/440L/C and EFI. It had a dead battery and he put a spare in and it started and ran. He then put a 2 amp trickle charger on it to top the battery off. He came back a couple hrs. later and it tested 12.5v and the pump started but no spark. The computer flashed a 5 code. He rode this sled for two yrs. with no trouble. The stator tested good. He tried another ecu and that did'nt work either. I don't have the book to find out the code. Thanks for any info.
